I've been hearing a lot of complaints from people about westbound I90 at the Idaho/Washington border. The freeway is reduced to one lane there until next Thursday, Sept. 23 and it's causing some long backups. The closure is in place to provide for the installation of the in-lane 'Weigh-In-Motion' equipment that is part of the weigh station also being construction there.
Traffic has been so backed up that you may want to avoid it if you can. Of course, you can't jump off at Stateline anymore, but you can always exit I90 at Pleasant View in Post Falls and take Wellesley over to Washington, or the back way to Liberty Lake.
